The Brügger & Thomet GL06 is a dedicated stand-alone shoulder-fired 40×46 mm (1.8 in) grenade launcher intended for military and police applications.

[1] The GL06 was developed in 2006[2] in response to a recent request from the police force of a leading European country which sought to obtain a less-lethal weapon for anti-riot application with the particular need for pin-point accuracy at standoff ranges (beyond 40 m (130 ft) for such scenarios) when firing impact rounds.

The Thun-based Brügger & Thomet (B&T) company provided its client with both a weapon and a special round, with the added benefit of compatibility with a wide array of lethal and less-lethal ammunition produced in the 40 mm (1.6 in) low-velocity class.

Although the LL06 was marketed as a variation of the GL06, the only difference is the bright yellow color of the frame, compared to the standard black of the GL06.

The GL06 is lighter and more compact than other stand-alone weapons of the same class (such as the US M79 or German HK69A1), yet it is capable of greater accuracy, tactical flexibility and has good ergonomics.
